The payback is well over all years Alternate ;i5: 5191,000 T1iis alternate adds a raimvatr.r collection and re-use system supplying non-potable water fur flushing pJmnbi,g fixtures throughout the facility, Tl1e payback on this s}=stem is over '100 years, Alternate ~6: SiD0 This alternate uses ivatcrless urinals, instead of conventionally plwnbed urinals Approval of this relatively small added cost ensures that water-conserving urinals will be installed Depending on usage and rvt3ter and sewer rates, Hie payback un this investment van be lctis than ~ years. Alternate 1#': S36S00 This alternate adds operable windows ur lieu of fixed windows in classrooms, Safety concerns and natural eentilation are considerationsnr acceptance of this alternate.. No payback numbers were generated since them. is no direct correlation to energy savings. As you lurow, payback pet°iods will decrease if the cost of providing electr'icih~/gas/water goes; up significantly, sirrce our life-cycle cost analyses are based on present rates with normal inflation INe understand Orange Countti='s rnmmitment to sustainable facilities as displayed in past projects, and we realize that the decision to fund alternates is not purely economic, especially since the high- perfornnmue system alternates add to the opportwniries for this educational facility to Uecomc a teaching tool for conservation of energy and water resources. Alternate #8: 5341,000 Also cretated at the request of the Board of Commissioners, this alternate adds a park and ride facility to the property adjacent to the proposed dassronm building. ]t is our understanding that grant-firndirng is available, and that buildung this alternate along with the rnllege's parking lots offers an oppor'hmitl= to ecinnomize on mobilization and material costs. It is our understanding that this infornnation will be discussed by the County Cemmnissioncrs wt ihc~ir August 22rnd meeting. Upon uur hearirng which alternates will be accepted and ttmded by floe BOCC, we will add those to the constntction contract with D4L.B to be incorporated into the overall project.
